Hi, As my GoTo is successfully finished (some cosmetic issues remain) I shoud focus my attention on planets' positions. I have proper source of information: fantastic book "Astronomical Algorithms" by Jean Meeus, thus I will sort the planets soon. But planets are not a challenge for me at this moment, they are just something obvious to do in my list. I have another idea and ambitious plan for next project within the year: locating and tracking the ISS to be able to make a video of its fly, not only transition. Similarly to other objects, I need some equations. I'm pretty sure they are available somewhere, because plenty websites or apps offer showing current position of the ISS. I will use this topic for sharing a progress ot the project.

Hey all, I cannot believe my luck. I was out on the 31st July practicing imaging Jupiter and Saturn with the my new ADC and ZWO Asi224MC. All of a sudden the ISS started to appear from the South West heading East. I quickly released the clutches on the mount and followed the ISS the best I could with the finder scope. Everything was set in sharp cap for the Jupiter capture, ROI was set to 320 x 240, 2x barlow plus ADC. I could not believe it out of 6500 frames I manged to find 13 frames, which I stacked. Second bit of luck, PIPP said it could not find an object, so I turned the option off and it ran without errors. The hero was AutoStakkert which sorted the frames to the front of the ser file. Composite of 3 images from my night: -
Another shot of the ISS as it passed over London on May 30th 2015. I think this is a slightly better shot than the one I posted a couple of days ago. This time the shutter speed was increased to 1/1250 second and the final image tweaked slightly in Photoshop. The method of capture was exactly the same as before with one person to drive the scope using the spotter scope and the other to rapid fire the camera at the right time. -

It's difficult to get a sense of scale in this astronomy game; but we try. So here are 8 pics of the ISS passing between Vega and Epsilon Lyra last night - which is a second's worth of my Canon 7D firing off as fast as it can. The background is a single 30 second tracked exposure for a bit of context. Details: Esprit 100 prime focus/Canon 7D:1/1000s ISO1600 +30s background. The trick if you want to try this is to use planetarium software to find out exactly when the ISS will be near a bright object, then pre-align and focus on or near that object, then wait for the ISS to appear in the finder before letting the shutter go in rapid mode. I also optimised pre-focus on the computer using the focus feature on Nebulosity before switching the camera back to stand alone mode. -
Hi, since quite some time I wanted to image a ISS moon transit. After my successfull double ISS solar transit I tought that could be another nice "thing to have". After all the fuzz about the super moon I decided "I need no sleep!". Since my Mak127 with my Nikon5100 is barely able to frame a "normal" moon, and not able to get a full moon on video, I used a Vivitar Series 1 Zoom adapted to my ZWO ASI 120MC on my NexStar SLT. That left me with quite some low resolution but I tried anyways. The night was very clear, there was just one thing which worried me. The big walnut tree could be in the way... I tried to measure and plann with stellarium and came to the conclusion that it would work from my terrace, sitting in the warm house imaging. First I wanted to image from a window in the first floor but that would have meant very bad air or let the room cool out heavyly. I took some nice shots around midnight and again slewed the scope to the expected position, just above the walnut tree. So I sleeped a bit and started to align the scope again at 4:00 MEZ, the transit was expected at 4:25:40. The moon was high enough still and I was quite sure it would work out. At 4:20 there was suddenly some strange shadows, then a trunk started to "move in", dang not enough time to pack the telescope and move to the garden. I hoped that I could make it to a gap in the tree in 5 minutes, but no.... So I ended up with a successfull imaged transit but having some shadows. I get now the chainsaw... ;-) Spot the ISS close to the center. The incredible 58fps of the ASI produces nearky a continous line of ISS outlines: So now I am tired but the outcome was despite my error quite ok. Just preparing a video showing the realtime transit. Cheers, Carsten

Green Flash while observing ISS. On the evening of 6th August 2016 I was watching the space station during a pass that took it almost through my zenith point. The sky was clear in Southwater, West Sussex during the entire crossing and I was not using any optical aids. Just after the greatest elevation point which was 87 degrees I observed a bright green flash that lasted a fraction of a second. The flash seemed to radiate out from the tiny bright spot of light of the space station. Somewhat surprised I noted the time as approximately 21:53:55 (taken from my cell phone and estimating time passed since the event.) As you may imagine, I was not prepared for this as during all the observations I have made since the ISS was launched, red is the only colour as it tracks east into earth’s shadow that I have ever witnessed. Can anyone offer me an explanation for what I saw?

Decided to try a handheld shot of ISS tonight as it was coming close overhead. This is the best shot from about 20 taken. Quite pleased, definitely will try again. ED80 + TV Powermate x 2 + Camera, single shot ISO1600 1/400 sec.- 17 replies

Everything seems too perfect for now. There's an ISS transit of the sun on late Wednesday morning, visible not too far away from me. Two weather forecasts currently suggest it'll be clear skies then. What could go wrong? Well, the weather forecast is for almost 2 days away so there's plenty of time for it to be wrong. Also, I haven't managed to ask my boss yet if I can take an early lunch to catch it... I need to plan where I want to see it from, the ground track passes through the Cotswold water park and there's various car parks in there I could try. Since I will be imaging from a car park, I can take more kit than I did for the Venus transit previously, and will go with both Ha and white light kit. So rig 1 will be PST capturing continuous video. Rig 2 will be DSLR with solar filter... but I'm not so confident in getting the timing just right for this one as it's only 0.8 second window! -

Saw the ISS as it rose from behind some clouds on the horizon, looking nice and golden in the sunset, I fancied I could just about make out an oblong shape to it through my large binoculars. Bit of a shallow short pass as it dipped below the rooftops when it was only half way across, but still special to know Tim was up there waving back at me.

My first attempt at the ISS - harder than I thought and much smaller, I would like to get in closer eventually. Dug the 150PDS out and 650D, 1 x 1/1250 at 3200 iso and a little tweak in PS, manually tracked. Short session but it was worth it

Hi, due to the exact prediction from calsky.com I was able to get a double solar transit of the ISS. I found a nice place for observing the two transits at maybe 200m from the calculated crossing of the central pathes. Technic was working flawlessly and so I could take two videos. Here is a video just the raw images: https://youtu.be/PFsZTPoM-ro The combined image is not aligned so far, so the "pilot" of the ISS seems a bit drunk. Ok it was the seeing and wind gusts. I will do a better aligned version when I got some time. Cheers, Carsten PS: Translation of the image caption: Place: South of Berlin, west of Rangsdorfer lake Time: 21 April 2016, first transit 14:27:31 distance to ISS 548km, second 17:39:13 distance to ISS 922km

A shot of the ISS as it flew over London last night. This is a huge improvement over the previous (and first) attempt last year but I think with a faster shutter speed it can be captured even better. Single 1000th of a second exposure at 6400 ISO with x2 Barlow (cropped).

The ISS was predicted to cross the Sun's disk at 15:53:29s on Wednesday. The event was visible in a 6km wide track near my location. Using a home made Baader solar filter on my SW 130 PDS and my DSLR with EOS Utilities I captured the moment, rather poorly. There are 2 GIFs. One is real time as the transit lasted a whole 0.55 seconds and the other is the same GIF slowed down a bit. With hindsight I could have got the image scale up but it was all a bit hectic.- 11 replies

So as per the title it's a hello again! Apologies I've been gone a while (2yrs) due to work commitments and moving home. After visits to the Kennedy Space Centre this summer and having just returned from the National Space Centre in Leicester (kids sleepover party), I dusted off my trusty little Dob and managed to get some fantastic views of Saturn for the family and even watched the ISS go by. Astro fun reinvigorated, clear skies fellow loungers.

Hello, I got some pics of the ISS last night. First pass I got a few decent frames. Then there was a second, brighter pass but the ISS went into the Earth's shadow overhead so only half a pass. Bit overexposed but got some good frames. Put it into a gif. Manually tracked with my 200p, the stock 2x barlow (so f/10). ASI120MM. Gain around 59. Shutter speed around 2.7 ms. Processed with PIPP then virtual dub. Thanks, Dan

The sky is clear today and to top it, there was this wonderful ISS pass today. It has been awful the past days so I took my 15 year old out after doing chemistry HW (lots of protests!) and asked him (nicely!) to sit in a reclining deck chair with a pair of binos to watch the ISS pass overhead for 5 minutes! **** Apparently I'm the best dad in the world for today! **** I took the image below with a Nikon 7000 + 10mm Fisheye on a iOptron SkyTracker 2. Approx. 5 minutes exposure at ISO 800. I'm osrry about the read streaks. That is me with my red light wondering to/from the camera. -
Hello, Tonight I had my first attempt at the ISS with my new camera (and laptop). I've taken images before but with the ASI120MM. I fancied colour and USB 3.0. It took 16,000 frames in around 200 seconds ! I definitely need a new barlow, thinking of either the posh celestron 2x or similar. The next big jump will be with the new telescope I'm going to make though. SW200p. Stock SW 2x barlow. ASI120MC-S. Manually tracked. Thanks, Dan

Hi Another attempt at the ISS. This time Canon 100d and 1200mm which actually is a 200 f4 with a 2x and 3x on it. Managed to bang off 50 frames when it was directly over head. What you get is a tiny little dot in the frame. (Currently given up trying to track it with the scope). Pipp to crop them all and then stack. First image is what I got from the stack of 50 drizzled at 3x, lots of CR which I got rid of by stretching the red away, then to B&W and play with registrax a lot. Result is second image. The lens is a very old M42 Pentacon 200mm but has very good optics, the teleconverter stack leaves a lot to be desired even for the £10 they cost me! So f24 1200mm @ 3200 ISO, 50 frames: half at 1/1000 half at 1/1600. I'm pretty pleased with the result. Please feel free to grab the png and play with the wavelets. Tom

Hello, I am having a first attempt at the ISS this afternoon. I will be using my 200p f/5 with a point grey webcam at prime focus. I have tested this out on a couple of smaller satellites and both times it has been overexposed (had the gain up high). Although they were so small I don't think I would have got any sort of shape if it were correctly exposed... The ISS will be Magnitude -3.4 tonight (considerably brighter than Jupiter even!) , so I was just wondering if I should stop down my scope? I am just worried that even with the gain right down it will still be overexposed. I know this is an abnormal imaging target, but if anybody has any advice it will be muchly appreciated! Merry Xmas, Dan

I took the best ISS images captured during yesterdays transit and ran them through Registax 6 to produce this image I think there are few artifacts present from the processing but I'm pleased with it
